Hey La Tech Do you think a ground wire would cause that? Sorry about that BOGIE IM not sure how to post a pic on here .

You have to be a bit careful when reading plugs, fouled plugs can be too much fuel, oil, too cold a heat range, missfiring, leaking valves, wiped out cam lobes.

The only thing the crud tells you is one or more of those things are not working right. When you get some messed up and others not it's a pretty (especially if this is 180 degree intake and the fouling is not linked to one plane or the other) good indicator that the ignition is messing up but this ain't proof positive. On the other hand if the fouling tends to be common on cylinders feeding from one of the two intake planes, it raises the odds that fueling isn't consistent on one side of the carb/TBI injectors.
